Table 1.

Total phosphoproteins, phosphorylation sites, kinases and scientific publications (PMIDs) curated by seven databases that capture protein phosphorylation information (UniProtKB, Phospho.ELM, PhosphoSitePlus, HPRD, PhosphoGrid, PhosPhAt and P3DB)

Total
Phosphoproteins* 28 158
Sites 125 896
Kinases* 689
Sites w/ kinase information 12 702
PMIDs 10 213

*The numbers of phosphoproteins and kinases are the numbers of distinct UniProtKB identifiers that were obtained by mapping the data to UniProtKB entries.
